True, but, as they furnish themselves the oxygen necessary for combustion, the mere fact of their eruption does not prove the presence of an atmosphere.
These jets of light, rapid in nature, and of frequent recurrence, they attributed to thunderstorms generated in the lunar atmosphere.
In 1715," replied the unknown, "the astronomers Louville and Halley mistook for lunar phenomena some which were purely terrestrial, such as meteoric or other bodies which are generated in our own atmosphere.
The nights are either brilliantly illumined or very dark, for if neither of the two moons of Mars happen to be in the sky almost total darkness results, since the lack of atmosphere
, or, rather, the very thin atmosphere
, fails to diffuse the starlight to any great extent; on the other hand, if both of the moons are in the heavens at night the surface of the ground is brightly illuminated.
However, were the forty-four thousand eight hundred and forty-seven cubic feet of gas of which we speak, all introduced into the balloon, it would be entirely filled; but that would not do, because, as the balloon continued to mount into the more rarefied layers of the atmosphere, the gas within would dilate, and soon burst the cover containing it.
The consumption of these articles would necessarily, little by little, diminish the weight to be sustained, for it must be remembered that the equilibrium of a balloon floating in the atmosphere is extremely sensitive.
The light and warmth of the sun probably exist in its atmosphere, and the spots which are so often seen on this bright orb, are supposed to be glimpses of the solid mass of the sun itself, that are occasionally obtained through openings in this atmosphere.
If this planet has any atmosphere at all, it is one of no great density, and its orbit being without our own, we can easily trace on its surface the outlines of seas and continents.

The short breathing from the rarefied atmosphere is called by the Chilenos "puna;" and they have most ridiculous notions concerning its origin.
The atmosphere resplendently clear; the sky an intense blue; the profound valleys; the wild broken forms: the heaps of ruins, piled up during the lapse of ages; the bright-coloured rocks, contrasted with the quiet mountains of snow, all these together produced a scene no one could have imagined.
The part that alcohol itself plays is inconsiderable when compared with the part played by the social atmosphere
in which it is drunk.
For some days past, Captain Bonneville had been made sensible of the great elevation of country into which he was gradually ascending by the effect of the dryness and rarefaction of the atmosphere
upon his wagons.
